I create video thumbnail like this in my app 

<pre><code> Bitmap myBitmap = BitmapFactory.decodeFile(pathOfFile);
 if(myBitmap == null) {
 myBitmap = ThumbnailUtils.createVideoThumbnail(pathOfFile, Thumbnails.MICRO_KIND);

 }
</code></pre>

Try this

</code></pre>

It's not too hard to do. Something like this:

<pre><code>int id = **"The Video's ID"**
ImageView iv = (ImageView ) convertView.findViewById(R.id.imagePreview);
ContentResolver crThumb = getContentResolver();
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(crThumb, id, MediaStore.Video.Thumbnails.MICRO_KIND, options);
iv.setImageBitmap(curThumb);
</code></pre>

The following code runs perfectly:

<pre><code>Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(file.getAbsolutePath(), MediaStore.Video.Thumbnails.MICRO_KIND);
</code></pre>

If you do not go through CURSOR or If you have only PATH or FILE OBJECTS, you can use :

<pre><code> public static Bitmap createVideoThumbnail (String filePath, int kind)
</code></pre>

I am trying to get a thumbnail of a video. But unfortunately i am not able to get thumbnails.

<pre><code> itmap bmThumbnail;

 // MICRO_KIND: 96 x 96 thumbnail
 bmThumbnail = ThumbnailUtils.createVideoThumbnail("file://" + catBean.tempImage,
 MediaStore.Video.Thumbnails.MICRO_KIND);
 img_icon.setImageBitmap(bmThumbnail);
</code></pre>
